个人简介
Over the past 10 years, Dumesic and his group have elucidated the fundamental surface chemistry involved in the catalytic conversion of biomass-derived compounds to fuels and chemicals. In addition, Dumesic and his group have developed new catalytic processing strategies and novel reactor configurations to achieve the selective transformation of biomass-derived reactants to targeted platform chemical intermediates, such as furfural, hydroxymethylfurfural, levulinic acid, and gamma-valerolactone (GVL). These platform molecules form the basis for a “bio-refinery” in which renewable biomass resources can be converted in a flexible manner to high-volume fuels and/or lower volume, higher values chemicals. During the past year, Dumesic and his group have focused attention on developing new methods to implement their bio-refinery concepts for real biomass feedstocks, including hemi-cellulose, cellulose, and lignin. For example, they have shown that alkylphenol compounds, such as sec-butylphenol, form a class of solvents that is effective for the selective extraction of furfural, hydroxymethylfurfural, and levulinic acid from aqueous solutions of mineral acids (e.g., sulfuric acid), allowing these acid catalysts to be used for deconstruction of hemi-cellulose and cellulose, followed by extraction of the reaction products, and completed by recycle of the mineral acids for further cycles of biomass deconstruction.
